B Correct answer
Explanation

Let total capital = C. Madhu invested 70% (0.7C) for 18 months. Deepti invested 30% (0.3C) for n months. Investment ratio: Madhu:Deepti = (0.7C×18):(0.3C×n) = 12.6:0.3n = 42:n. Since Deepti gets 40% profit and Madhu gets 60%, their profit ratio is 40:60 = 2:3. Therefore, 42/n = 3/2 (inverse ratio). Solving: n = 42×2/3 = 28 months. Option B is correct.
